I received my iPhone 16 Pro on 9/20. Restored my old phone into it...which took 2 hours. Since that time there have been 3 occasions (maybe 4) where there was a software update that I needed to do. It updates like any other update, then I'm greeted with the "Hola" or "Hello" screen as if I'm opening my phone for the first time. When I swipe up it tells me that my phone has been updated to iOS 18 (not 18.1 or 18.0.1)...and it's back to normal. Why is this happening and is it normal?
